Ovarro first devised a solution with Rogowski coils. Rogowski coils are commonly used to accurately monitor medium- and low-voltages in precision welding systems, arc melting furnaces, in short-circuit testing of electric generators and as sensors in protection systems of electrical plants. But, aside from the Rogowski coils, remote telemetry units (RTUs) were needed for the capture, storage and interpretation of vast amounts of data from physical assets in the network.
RTUs are now a critical part of most power generation and distribution operations, and are essential for today and tomorrow’s smart grids. For Juva, Ovarro recommended the Datawatt Smart Grid (DSG) series, designed for operation in the water, energy and industrial markets. The design operates under two main principles — flexibility and maximum security.
Flexible characteristics of the DSG include its ability to implement a variety of protocols in real-time, including IEC104, COAP and Modbus with other protocols available on request. New protocols can be easily created through the Linux operating platform and C# programming language, while programmable logic controller (PLC) programs can also be made with the latest standard from Codesys based on IEC61131-3 — this standard is the industrial protocol for control programs and is used by many national and international organisations and companies.
